Follow other avatars

I'm brand new at scripting, although I think I'm catching on fast. Anyway, I've been playing with this script for hours, but I can't manage to make it work. So, does anyone know how to make the Open Shifting Float and Follow Script by Foolish Frost follow other avatars? I don't want the object to push them or cage them, just to bob around and follow them. It's for a magic spell, but I honestly am very lost trying to do this.

Any help would be greatly appreciated!

you're looking at using llSensorRepeat with a reasonable polling rate (about 3 seconds is decent for non-griefing followers), and then using llMoveToTarget to move your object there by feeding it the sensor's results with the llDetectedKey() call.

I'm still lost.

What Senuka said is correct...let me see if I might be able to help in a way that gets you at least slightly un-lost. It also helps us if you post code that you're trying to complete so that we can help you iron out any errors you have in it. Please post them within PHP tags though--helps us read it easily

Anyway...

Your object will want to use an llSensorRepeat() function on about 3 second intervals to detect the position of the avatar it is trying to follow...

...in the Sensor() event, you'll grab the sensor info...getting the detected location of the avatar you're looking for (identified by llDetectedKey()) and then using an llMoveToTarget() to get your follower object there.

Well I've screwed up the code so much I'm just repasting the original.

// OFFSET is the position of your pet in relation to it's owner's position.
// For example, in the default setting below, "vector offset =<-1,0,1>;"
// I.E. (x,y,z), the -1 puts it 1m back behind owner, the 0 means don't have
// it stay left or right, and 1 means have it stay 1m above it's owner.  
// So, if you wanted the script to make it follow directly in front of you,
// and to the left, then you would change it to "vector offset =<1,1,0>;"

        llMoveToTarget(pos+(offset+currentoffset)*llDetectedRot(0),.3);
        if (currentyshift>=0)
        {
            currentyfacing = currentyshift;
        } else {
            currentyfacing = currentyshift*-1;
        }
        
        llLookAt(pos+<0,0+(currentyfacing*.33),1+bobbing>, 1 , 2); 
        
        currentbob = currentbob +1;
        if (currentbob == 16)
        {
            currentbob = 0;
        }
        
        if(timeset==0)
        {
            timeset = 1;
            llSetTimerEvent(((llFrand(shifttime)+llFrand(shifttime)+llFrand(shifttime))/3)*2);
        }
        
        
    }
    
        timer()
    {
        timeset = 0;
        currentyshift = llFrand(yshift*2)-yshift;
        currentxshift = llFrand(xshift*2)-xshift;
    }
}

I want that to follow who I say by giving a follow (name) command on a channel of my choice. :-\

You will need to make it such that it listens to the owner and then when they specify the name of an avatar starts a sensor and then moves to the specified target. Partial name matching isnt difficult. You will probably need it to follow the owner so it stays in chat range when its not following someone.
